Gardeners can effectively deter slugs and snails this summer using natural methods recommended by pest control specialists, avoiding harsh chemicals. Rising temperatures and summer showers create ideal conditions for slugs, increasing their metabolism and reproduction, making gardens a prime target.
Copper Tape: A Reliable Barrier
Ryan Kaila from Kingfisher Direct and Mosh Latifi of EcoCare Pest Management both advocate for copper tape. Ryan explains: "I recommend using copper tape around bin stores and planters to deter slugs. Slugs love damp, sheltered spaces, and in summer they can often be found around food waste bins, compost bins and recycling areas." He advises applying a complete, unbroken strip around bases, keeping the area free of weeds and leaves that could serve as bridges.
Mosh adds: "Copper tape is the most reliable and long-lasting natural slug deterrent available. When slugs come into contact with copper, a mild electrochemical reaction occurs with their mucus, creating an unpleasant sensation that makes them turn back." He notes it stays in place all season, unlike coffee grounds or eggshells that wash away.
Eggshells: Simple Kitchen Waste Solution
Martin Chaplin, Head of Horticulture at Hedges Direct, recommends crushed eggshells. "The rough, sharp texture creates a barrier that slugs are often reluctant to cross," he says. Allow eggshells to dry completely, crush into coarse pieces, and scatter around plant bases. Reapply after heavy rain. "They're an easy way to recycle kitchen waste while helping to protect young plants throughout the summer," he adds.
Sheep Wool: Physical and Absorbent Deterrent
James Copley, CEO of Copley Pest Solutions, suggests sheep wool as his top natural method. "Slugs rely on smooth, moist surfaces to move, and sheep wool disrupts their ability to move freely. It is dry, tangled, and uncomfortable, and it absorbs moisture around plant bases, making the area less inviting." He recommends wool pellets or raw wool, placed in a thick continuous ring around plants, refreshed if compacted.
Coffee Grounds: Aroma and Texture Repellent
Chris Bonnett of GardeningExpress.co.uk highlights coffee grounds. "Sprinkling coffee grounds around your plants is an effective way to deter slugs and snails as they don't like the strong aroma and the texture is also unpleasant for them to crawl over." Like eggshells, coffee grounds enrich the soil as they decompose. He advises opting for natural deterrents to avoid harming other wildlife.
